- Abstract:
- To investigate the impact of water supply network partition on chlorination strategies, an optimization method was developed using simulation-optimization framework to effectively manage residual chlorine following network partition. The results based on the J case pipeline network revealed a significant trade-off among the total chlorine dosage within the network, the number of chlorination stations, and the complexity of the chlorination. Under the premise of ensuring water quality safety at all nodes, the optimized scheme following network partition achieved a chlorine consumption reduction of up to 46.8% compared to the scheme before partition. The implementation of network partition is likely to adversely affect the original chlorination scheme. A more adaptable secondary chlorination approach can mitigate the potential negative impact on water quality at critical nodes following the network partition. To ensure the safety of water quality following the implementation of network partition, it is imperative to reassess and readjust the chlorination strategy, including a moderate increase in the total chlorine dosage. It is recommended that the impact of network partition on chlorination should be incorporated into the cost-benefit analysis process when planning the network partition, so as to address the conflicting relationship between leakage control benefits and increased chlorine consumption.
